Seems to depend on who is your shipper. UPS is CRIMINAL when shipping into Canada from the US. Conversely, I have NEVER been charged ANYTHING when receiving something from the US via USPS.
Agreed, the part the Government takes is nothing compared to the "brokerage fee", but it is much more faster than USPS/Canada Post. Too bad there are no resellers for BFL in Canada.
This is helpful for figuring out the total cost of some things:
